Key Parameters

Substitute Part Grouping Explanation

Substitution for the CSRF2512JK5L00 is determined by the following critical parameters:

• Resistance value: 5 mOhms (exact match required)
• Power rating: 2W (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Metal Foil (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 170°C (exact match required)
• AEC-Q200 automotive qualification (required for automotive applications)

Tolerance and product status may vary between the main part and substitutes. The CSRF2512JK5L00 (±5% tolerance, obsolete) can be replaced by parts with equal or tighter tolerance specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

CSRF2512JT5L00 is a direct functional equivalent to the CSRF2512JK5L00. Both parts share identical electrical and mechanical specifications with ±5% tolerance. The primary difference is product status: CSRF2512JT5L00 is active and available, while CSRF2512JK5L00 is obsolete. This part is suitable for direct replacement in existing designs.

CSRF2512FT5L00 is an upgraded alternative with tighter tolerance (±1% versus ±5%). All other electrical and mechanical parameters remain identical. This part is recommended for applications requiring improved resistance accuracy. CSRF2512FT5L00 is active and widely available.

Both substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating, ensuring compatibility with automotive and moisture-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can CSRF2512JT5L00 be used as a direct replacement for CSRF2512JK5L00?

A: Yes. Both parts have identical resistance (5 mOhms), tolerance (±5%), power rating (2W), package (2512), composition (metal foil), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 170°C). The only difference is packaging format and product status. CSRF2512JT5L00 is the active equivalent.

Q: What is the difference between CSRF2512JT5L00 and CSRF2512FT5L00?

A: The primary difference is tolerance specification. CSRF2512JT5L00 has ±5% tolerance, while CSRF2512FT5L00 has ±1% tolerance. All other parameters—resistance value, power rating, package, composition, temperature coefficient, and operating temperature—are identical. CSRF2512FT5L00 is suitable for applications requiring higher accuracy.

Q: Are these parts suitable for automotive applications?

A: Yes. All three parts (CSRF2512JK5L00, CSRF2512JT5L00, and CSRF2512FT5L00) carry AEC-Q200 automotive qualification and are designed for automotive current sense applications.

Q: What is the difference between bulk and Tape & Reel packaging?

A: CSRF2512JK5L00 is supplied in bulk packaging, while CSRF2512JT5L00 and CSRF2512FT5L00 are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes. Both packaging formats contain the same component.

Q: Can I use CSRF2512FT5L00 in place of CSRF2512JK5L00 in existing designs?

A: Yes. CSRF2512FT5L00 is electrically and mechanically compatible. The ±1% tolerance is tighter than the original ±5% specification, making it a suitable upgrade. No design changes are required.

Q: Are all three parts RoHS compliant?

A: Yes. CSRF2512JK5L00, CSRF2512JT5L00, and CSRF2512FT5L00 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
